Adjustable Beamsplitter Mount of Side Drive 5BM59T-1 complements our range of Series T
mounts with additional features, e.g. pick-hollows, or yet more
stabilized spring. The style of the mount relates to such units as
5APH59T-1 and 5MBM21-1. The mount accepts optics 25.4 mm in diameter. Optics is stopped by a rest-flange
inside the central aperture of the platform, and is secured by a steel
hex fixing screw. The fixing screw has a hard plastic tip to prevent
damage to the optics. To allow an unimpeded access for your fingers
there are two pick-hollows. No more hassle and stains while
picking the optics out... No more dropping the optics before you put it
in securely. Pick-hollows form two contact points in the aperture.
Clamped by the fixing screw, optics rests against these two points, so
its position stays definite. Angular adjustment range of tilt/tip is ±2°. Side control of tilt and tip is done by two stainless steel fine adjustment screws with pitch of 0.25mm. The screws push rolling balls against hardened seats, ensuring smooth operation and sensitivity of 3 arcsec.
Large knobs of the screws ease the strain on you fingers that this
stabilized system might cause. Both screws protrude from the top. This
control from a side allows easy access, and dense placement of
surrounding instruments. The platform is preloaded against the base with
L-shaped flat spring of our original design which renders the great
stability and eliminates induced polarization. Three M4 tapped
holes on the sides of the base and on its back allow a variety of
mounting configurations, e.g. horizontal and vertical. The holder easily
mounts on posts and bases. The holder is made of black anodized
aluminium. L-shaped spring is made of high quality stainless spring
steel.
